Key result
Moderate blood flow restriction with KAATSU allowed the participant to reach the anaerobic threshold at a 41.2% lower exercise intensity and with lower heart rate and perceived exertion, while maintaining similar muscle activation compared to exercise without KAATSU.
Why the study?
The study examined the effects of moderate blood flow restriction due to KAATSU on rectus femoris activation, heart rate, and ratings of perceived exertion while cycling at an intensity just below the anaerobic threshold.
Does moderate blood flow restriction induced by KAATSU alter muscle activation, heart rate, and perceived exertion during low-intensity aerobic exercise in a healthy young male?

Does moderate blood flow restriction induced by KAATSU alter muscle activation, heart rate, and perceived exertion during low-intensity aerobic exercise in a healthy young male?
Effect estimate: 41.2% lower
Absolute Event Rate: 70% vs 120%
Low-intensity aerobic exercise with KAATSU elicits similar muscle activation at lower physical and perceived effort compared to exercise without KAATSU, suggesting potential utility as a low-burden method for cardiac rehabilitation.
May support lower-burden aerobic training in CVD rehab; leaves open efficacy and safety in patients.
[Objective] We examined the effects of moderate blood flow restriction due to KAATSU on rectus femoris activation, heart rate (HR), and ratings of perceived exertion (RPE) while cycling at an intensity just below anaerobic threshold (AT).

Mizushima et al. (2020) conducted a case report in Healthy (n=1). KAATSU (moderate blood flow restriction) vs. Without KAATSU was evaluated on Exercise intensity just below anaerobic threshold (AT) in Watts (41.2% lower). Moderate blood flow restriction with KAATSU allowed the participant to reach the anaerobic threshold at a 41.2% lower exercise intensity and with lower heart rate and perceived exertion, while maintaining similar muscle activation compared to exercise without KAATSU.
